Unisonunison-fs
Mount the Unison brain as a real local directory (FUSE on Linux, NFS on macOS) and search it semantically with sgrep - agents that understand files need no integration at all.
unison-fs mounts the brain as a real local directory - FUSE on Linux, embedded NFS on macOS (no kernel extension) - with a local SQLite cache and background sync. Editors, scripts, and agents that already understand files work without any integration.

unisonfs mount ~/brainRust 1.80+ to build from source. The mounted tree mirrors the path namespaces - /private/, /workspace/, plus read-only /system/. Conflicts surface as stale-hash errors rather than silent overwrites, same as the API contract.
MCP server
Add the Unison brain to Claude Code, Cursor, Codex, or any MCP client with @unisonlabs/mcp - a deliberately curated tool set so agent context stays lean.
